I also ignored the Tape functions on the OP-1 when I first got mine, focusing more on the synths.
I did however immediately start messing w/ the Tombola sequencer. It's really nice for ambient stuff. The Finger sequencer was released shortly after I got the OP-1 so I was having some fun w/ the animated gorillas and dudes.
The most obvious use for Tape is if you're on the road somewhere and want to record an idea quickly, before you forget it. Beyond that, it came to life for me as I got into musique concrete-inspired production techniques. I'm still a beginner at that stuff but am having fun w/ it.
Anyway, take your time and have fun w/ your new OP-1. Its not like the Tape is going to get up and walk away from you if you don't use it. It'll be there for you when you're ready for it.
